Cross-Site User Attribute Processing for Targeted Web Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems are limited in their ability to utilize operation information from multiple websites to perform useful processing, such as providing targeted advertisements or modifying web pages based on user behavior across sites.
Innovation Solution
An information processing device that receives and analyzes operation information from multiple sites, acquires user attribute values, and performs processing such as selecting advertisements or modifying web pages using these attribute values, incorporating learning information to estimate user attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operation information from multiple sites is collected and processed, then user behavior analysis capability is improved, but information processing complexity increases
Solution Approach 1:
The patent segments operation information processing by site, where each site's operation information is processed independently to extract site-specific attribute values. This modular approach allows parallel processing of multiple sites without increasing overall system complexity, as each site's data is handled through standardized extraction and integration procedures.
Solution Approach 2:
The patent introduces an intermediary information processing device that acts as a mediator between multiple sites and the analysis system. This device collects operation information from various sites, standardizes the data format, and presents unified user attribute values to the analysis system, thereby shielding the complexity of multi-site data integration from the core analysis functionality.
2Measurement precision
If user attribute values are acquired from multiple sites, then advertisement targeting accuracy is improved, but data processing time increases
Solution Approach 1:
The patent performs preliminary extraction of user attribute values from operation information at each site before integration. By pre-processing and identifying key attribute values (such as user preferences, behavior patterns) from multiple sites in advance, the system reduces the computational burden during advertisement selection, thereby minimizing additional processing time while maintaining high targeting accuracy.
Solution Approach 2:
The patent merges attribute values from multiple sites into a unified user profile by identifying and consolidating common attributes. This combination approach avoids redundant processing of duplicate information across sites and creates a comprehensive yet efficient user representation that enhances advertisement targeting without linearly increasing processing time with the number of sites.

AI summary
Conventionally, useful processing cannot be performed using operation information on two or more sites. With an information processing device that includes: an operation information reception unit that receives one or more pieces of first operation information regarding a user on a first site, and one or more pieces of second operation information regarding the user on a second site; an attribute value acquisition unit that acquires a first attribute value of the user, using the one or more pieces of first operation information, and acquires a second attribute value of the user, using the one or more pieces of second operation information; and a site processing unit that performs predetermined processing on the first site or the second site, using the first attribute value and the second attribute value, it is possible to perform useful processing using operation information on two or more sites.
